Simple approximation for solving a right triangle
John
Suppose you have a right triangle with sides a, b, and c, where a is the shortest side and c is the hypotenuse. Then the following approximation from [1] for the angle A opposite side a seems too simple and too accurate to be true. In degrees, A ≈ a 172° / (b + 2c). The approximation above only involves simple […] The post Simple approximation for solving a right triangle first appeared on John D. Cook .
